A Li- (Lithium ion) placed at the location <1.0, -0.4, -0.9> m experiences a force of <0, 2.88e-14, 1.53e-14>N due to a charge Q located at <1.0, 0.35, -0.5> m. What is the electric field which causes this force on the Lithium ion? Answer must be a vector. What is the magnitude and sign of charge Q?
